Given P(X) = 0.35, P(Y) = 0.45, and P(Y|X) = 0.25, what are P(X and Y) and P(X or Y)? P(X and Y) = 0.0875, P(X or Y) = 0.7 P(X and Y) = 0.0875, P(X or Y) = 0.7125 P(X and Y) = 0.8, P(X or Y) = 0.7 P(X and Y) = 0.8, P(X or Y) = 0.7125

An is a number that is written without a component. it is a number that is either or . an exponent is a or a number that another number is being to. the number that is being raised to a is called the . the or power tells you how many times to the base by . if an exponent is fractional then ask yourself the question: what when multiplied by itself a certain number of times will equal the number?
